The LED lights sold in this listing are 12 Volt DC LED lights. They are designed to be connected to a 12V DC power source such as a 12V battery. DO NOT attempt to connect or plug these lights into a 110V power outlet such as a standard wall outlet found in your home as it will burn these lights out and void the returns policy. LED lights that are designed to be plugged into a standard North American wall outlet need to be 110-120 Volts. We do sell 110 Volt LED rope lights in our store.
